Question 9

of the extent of exposure to the chemical hazards, physical or biological agents (or adverse ergonomic situation) in the workplace. This often involves measurement of the personal exposure of a worker to the hazard/agent in the workplace, particularly at the relevant interface between the environment and the body, e.g. breathing zone, hearing zone, and assessment of the data in terms of recommended occupational exposure limits (OELs), where such criteria exist.

Answer 9

Evaluation

Question 10

OEL

Answer 10

occupational exposure limits

Question 11

of the chemical, physical or biological agent - or adverse ergonomic situation, by procedural, engineering or other means where the evaluation indicates that this is necessary.

Answer 11

Control

Question 12

this covers both clinical practice (doctors) as well as nursing and is concerned with the effect of work on health and health on work. This involves the prevention of health problems, promotion of healthy living and working conditions as well as the diagnosis and treatment of work related ill health.

Answer 12

Occupational Medicine

Question 13

focuses essentially on a preventative approach through the minimisation of exposure to chemical, physical and biological agents in the work environment and the adoption of good ergonomic practices.

Answer 13

Question 14

concerned with the statistical study of disease patterns in groups of individuals.

Answer 14
